Product Q&A

Q:How do I identify the battery material?

Check the battery body voltage: 3.2V indicates LiFePO4, while 3.6V or 3.7V indicates Li-ion or Li-polymer. You can also ask the manufacturer.

Q:Can I use this board for my battery?

Ensure the number of cells in series matches your battery pack. The protection board must correspond to the same series count.

Q:What material is your battery?

We provide protection boards for LiFePO4 and Li-ion. Please specify if you need a board for LiFePO4 due to different electric parameters.

Q:Do we need cell balance?

Yes, because cells in parallel and series cannot be identical. Balance function ensures similar performance groups operate correctly.

Q:Is there a Minimum Order Quantity (MOQ)?

No MOQ. We accommodate different requirements and provide various capacities and sizes. OEM/ODM is welcome.
